This study aimed to evaluate the impact of carboxymethylation on the structural and functional properties of β-glucan derived from the pathogenic oomycete Pythium insidiosum. β-Glucan was extracted and subjected to carboxymethylation (CM-glucan), with structural changes analyzed using C and H NMR spectroscopy. The modified β-glucan's ability to adsorb mycotoxins, specifically deoxynivalenol (DON) and T2 toxin, was assessed through in vitro adsorption assays.

- A 3.5-year-old mixed-breed dog was diagnosed with invasive candidiasis, leading to systemic Candida infection and multi-organ colonization, following a limb injury.
- Despite antibiotic treatment, the dog died three days later, with necropsy revealing extensive pyogranulomas in the liver, stomach ulcers, and lung consolidation associated with Candida albicans.
- The case highlights a rare occurrence of invasive candidiasis in dogs, noting that neutropenia from sepsis and antibiotic use could have facilitated the yeast's invasion and spread to various organs.
This systematic review compiles reports of clinical pythiosis in horses, mules and donkeys from 1960 to 2023 worldwide, focusing on Brazil. We searched databases and included 71 articles detailing clinical characteristics, geographic distribution, epidemiology, diagnostic methods, therapies, and outcomes. The results showed that publications on equine pythiosis have significantly increased since 2010.

Susceptibility tests of P.

This study aimed to enhance the understanding of pythiosis epidemiology, map the distribution of horse body lesions, and investigate the correlation between these lesions and warm body surface areas, potentially implicating hematophagous vectors in the disease's transmission. A prospective study was conducted on equids in the Pantanal Mato-grossense and adjacent areas from 2012 to 2022, with 112 horses and three mules diagnosed with pythiosis.
